To design robust domain boundaries in microservices, apply Domain-Driven Design (DDD) to define bounded contexts and use context mapping. This isolates domain logic and structures complex distributed systems for scalable service interactions.

The best way to handle distributed transactions across microservices is implementing the Saga pattern. Sagas coordinate sequences of local transactions with compensating actions, ensuring data consistency across services without relying on distributed locks or two-phase commits.

Use CQRS and event sourcing when you need scalable read/write models and a complete audit trail of state changes. CQRS separates command and query responsibilities, while event sourcing persists state as a sequence of domain events, ideal for complex domain logic.

Yes, you can apply enterprise architecture patterns for multi-tenant SaaS applications. These patterns provide specific guidance for multi-tenant architectures, addressing tenant isolation, API integration, and scalable data models tailored for SaaS environments.

Migrate a monolith to microservices by using DDD context mapping to identify bounded contexts and extracting them into independent services. This pattern provides real-world guidance to incrementally decouple modules while maintaining API integration.

You need an API gateway and service mesh in distributed systems to manage external routing and internal east-west traffic. These patterns provide structured communication, observability, and resilience across microservices.
